As Ramesh and others have remarked, the Left’s buzzword du jour is once again that the Right “lies.” Rush Limbaugh is a big fat liar! Bush lied! Romney lies! Paul Ryan is a lying liar! The entire right wing of American politics is composed of sociopathic prevaricators, brazenly unleashing their chicanery on a gullible, unsuspecting public.

Such playground rhetoric is, of course, old news to those of us who have been interacting with the Left since (in my case) 1967. No contradicting statement is ever made in good faith; no information except that already accepted by the Left can possibly be true (unless the media-driven politburo decrees a new, higher truth, in which case everyone simply pivots and moves on); and all misstatements are evidence of maleficence.

But this year, the lying liars meme has been taken to a whole new level. As we saw in the first Romney-Obama debate, the president essentially argued that Romney was lying about his tax plan — even with Romney standing there, right across from him, explaining to the nation what it was. In other words, the GOP candidates aren’t just lying about the details of the Democrats’ dismal record, but are lying about themselves, as if they were Siegfried at the end of act one of Goetterdaemmerung, pretending to be Gunther as he’s rudely wooing Bruennhilde.
